* INCLUDES 'WHY IT MATTERS' FEATURE * This paper, published in a Special Issue of the journal Ecological Indicators to mark 20 years of data collection at ECN terrestrial sites, presents an analysis of the temporal relationships between soil solution chemistry and parameters thought to regulate Dissolved Organic Carbon (DOC) production. Data from both ECN and Forest Level II plots were used.

* INCLUDES 'WHY IT MATTERS' FEATURE * The authors used photographs collected as part of the ECN monitoring at our Cairngorm site to determine how the duration of snow cover has changed in recent years.

* INCLUDES 'WHY IT MATTERS' FEATURE * This paper, published in a Special Issue of the journal Ecological Indicators to mark 20 years of data collection at ECN terrestrial sites, uses detailed ECN vegetation data. The data suggest that species richness has increased at the sites during the period 1993-2012

* INCLUDES 'WHY IT MATTERS' FEATURE * The authors used ECN data for two sites in Scotland to reveal correlations between declining ground beetle (Coleoptera: Carabidae) populations and phenological changes (the timing of natural events).
